"Princess, I'm so glad you're awake!"
"..."
"I'll inform the king," a butler says as he rushes out excitedly that I've woken up.
"Tsk, damn it!" The personality aspect I have here is extreme vanity and arrogance. I have all my memories from age 7 and up.
I am a princess with a terminal illness that will kill me when I turn 18. This illness is called the "Blue Dusk" and occurs with people born during the blue moon in this world, which happens every 18 years.
And when it occurs again, the person dies, which means that in the next blue moon, I will die, and no one can do anything about it.
And exactly for this reason, I in this world was very spoiled by the family, since my fate is sealed.
At least I know who the Yandere is, and the butler who was with him, his name is Aiden, and I've known him since my childhood.
